dc.descriptionTanisaki introduced generating sets for the defining ideals of the schematic intersections of the closure of conjugacy classes of nilpotent matrices with the set of diagonal matrices. These ideals are naturally labeled by integer partitions. Given such a partition $λ$, we define several methods to produce a reduced generating set for the associated ideal $I_λ$. For particular shapes we find nice generating sets. By comparing our sets with some generating sets of $I_λ$ arising from a work of Weyman, we find a counterexample to a related conjecture of Weyman.
